N.A.T. has launched the DC versions of the NAT-PM family of power modules for MicroTCA

N.A.T. announces the NAT-PM-DC780, the DC version of the two N.A.T. PMs for MicroTCA applications, offers power conversion from two -48VDC input sources to 16 independent 12 V channels for payload power and 3.3 V for management power. This PM provides Shared Management Power (SMP) - backup power- for other PMs in the system and is designed to run up to 12 AMCs, 2 Cooling Units and 2 MCHs.

The NAT-PM-DC780 is a high-density, high-efficiency PM for MicroTCA applications. Supplying 780W or 840W it is the market’s most efficient PM to run today’s complex communication systems that use latest processor generations of large memory capacity and an increased number of Advanced Mezzanine Cards (AMC). The NAT-PM-DC780 provides electrical support for the maximum expected workload of 12 Advanced Mezzanine Cards (AMCs), 2 Cooling Units (CUs) and 2 MicroTCA Carrier Hub (MCH) modules.

EMMC: The PM includes a robust Enhanced Module Management Controller (EMMC) that interfaces the power control functionality via an Intelligent Platform Management Bus (IPMB) to the MicroTCA Carrier Hub (MCH).

Redundancy and Load Sharing: The NAT-PM-DC-780 supports redundancy as well as load sharing modes as in accordance with the MicroTCA specification. In case of an input power supply failure the onboard EMMC can be provided by SMP power from other PMs, so that the MCH is able to analyze root cause failure.

LED Indicators: Besides the standard indicator leds for hot-swap, failure and heartbeat the NAT-PMC-DC780 has a unique light bar indicator, showing the total power load of the module on a scale from 0 to 100% in real time.

Applications: The NAT-PM-DC780 is a hot swappable, fully redundant and highly efficient PM. The module’s single-width design offers perfect thermal performance and is therefore ideally suited for all air cooled MicroTCA solutions. The PM’s software has been developed and de-bugged using the MCH from NAT as a reference tool. It is fully compatible with any cards or modules insertable into a MicroTCA chassis. Application areas are commercial-, military-, and tele- communications, automation test equipment, medical, video demand, security, industrial machine control and other clustered computing ap­plications.
